The RDi-515 drill machine is developed to meet the special requirements of steel fabricators. With a maximum material width of 640 mm and a hight of 340 mm, it can process steel beams, angles, channels and box sections. With 15 tools available in the automatic tool changer it is capable of carbide drilling, scribing, thread-cutting and centre-marking.

This brand new generation of compact drill machine is designed to be more stable and affordable for the small Steel builder. It is robust and has low-vibrations, water- cooled and direct drive drill axes. The W-axis drill is mounted on a specially-designed sliding column together with the horizontal clamp to make it extra compact and stable. Added to this are the high-performance servo motors and ball screw spindles which make it a fast and high-precision machine.

These RDi-515 machines can be combined with a band saw and in- and out feed roller conveyors and cross transports.
